CreateDBInstanceReadReplica
Creates a new DB instance that acts as a read replica for an existing source DB instance or Multi-AZ DB cluster. You can create a read replica for a DB instance running Db2, MariaDB, MySQL, Oracle, PostgreSQL, or SQL Server. You can create a read replica for a Multi-AZ DB cluster running MySQL or PostgreSQL. For more information, see Working with read replicas and Migrating from a Multi-AZ DB cluster to a DB instance using a read replica in the Amazon RDS User Guide.
Amazon Aurora doesn't support this operation. To create a DB instance for an Aurora DB cluster, use the CreateDBInstance
operation.
All read replica DB instances are created with backups disabled. All other attributes (including DB security groups and DB parameter groups) are inherited from the source DB instance or cluster, except as specified.
Important
Your source DB instance or cluster must have backup retention enabled.

- PreSignedUrl
-
When you are creating a read replica from one AWS GovCloud (US) Region to another or from one China AWS Region to another, the URL that contains a Signature Version 4 signed request for the
CreateDBInstanceReadReplica
API operation in the source AWS Region that contains the source DB instance.This setting applies only to AWS GovCloud (US) Regions and China AWS Regions. It's ignored in other AWS Regions.
This setting applies only when replicating from a source DB instance. Source DB clusters aren't supported in AWS GovCloud (US) Regions and China AWS Regions.
You must specify this parameter when you create an encrypted read replica from another AWS Region by using the Amazon RDS API. Don't specify
PreSignedUrl
when you are creating an encrypted read replica in the same AWS Region.The presigned URL must be a valid request for the
CreateDBInstanceReadReplica
API operation that can run in the source AWS Region that contains the encrypted source DB instance. The presigned URL request must contain the following parameter values:-
DestinationRegion
- The AWS Region that the encrypted read replica is created in. This AWS Region is the same one where theCreateDBInstanceReadReplica
operation is called that contains this presigned URL.For example, if you create an encrypted DB instance in the us-west-1 AWS Region, from a source DB instance in the us-east-2 AWS Region, then you call the
CreateDBInstanceReadReplica
operation in the us-east-1 AWS Region and provide a presigned URL that contains a call to theCreateDBInstanceReadReplica
operation in the us-west-2 AWS Region. For this example, theDestinationRegion
in the presigned URL must be set to the us-east-1 AWS Region. -
KmsKeyId
- The AWS KMS key identifier for the key to use to encrypt the read replica in the destination AWS Region. This is the same identifier for both theCreateDBInstanceReadReplica
operation that is called in the destination AWS Region, and the operation contained in the presigned URL. -
SourceDBInstanceIdentifier
- The DB instance identifier for the encrypted DB instance to be replicated. This identifier must be in the Amazon Resource Name (ARN) format for the source AWS Region. For example, if you are creating an encrypted read replica from a DB instance in the us-west-2 AWS Region, then yourSourceDBInstanceIdentifier
looks like the following example:arn:aws:rds:us-west-2:123456789012:instance:mysql-instance1-20161115
.
To learn how to generate a Signature Version 4 signed request, see Authenticating Requests: Using Query Parameters (AWS Signature Version 4) and Signature Version 4 Signing Process.
Note
If you are using an AWS SDK tool or the AWS CLI, you can specify
SourceRegion
(or--source-region
for the AWS CLI) instead of specifyingPreSignedUrl
manually. SpecifyingSourceRegion
autogenerates a presigned URL that is a valid request for the operation that can run in the source AWS Region.This setting doesn't apply to RDS Custom DB instances.
Type: String
Required: No
-
- ProcessorFeatures.ProcessorFeature.N
-
The number of CPU cores and the number of threads per core for the DB instance class of the DB instance.
This setting doesn't apply to RDS Custom DB instances.
Type: Array of ProcessorFeature objects
Required: No
- PubliclyAccessible
-
Specifies whether the DB instance is publicly accessible.
When the DB cluster is publicly accessible, its Domain Name System (DNS) endpoint resolves to the private IP address from within the DB cluster's virtual private cloud (VPC). It resolves to the public IP address from outside of the DB cluster's VPC. Access to the DB cluster is ultimately controlled by the security group it uses. That public access isn't permitted if the security group assigned to the DB cluster doesn't permit it.
When the DB instance isn't publicly accessible, it is an internal DB instance with a DNS name that resolves to a private IP address.
For more information, see CreateDBInstance.
Type: Boolean
Required: No
- ReplicaMode
-
The open mode of the replica database: mounted or read-only.
Note
This parameter is only supported for Oracle DB instances.
Mounted DB replicas are included in Oracle Database Enterprise Edition. The main use case for mounted replicas is cross-Region disaster recovery. The primary database doesn't use Active Data Guard to transmit information to the mounted replica. Because it doesn't accept user connections, a mounted replica can't serve a read-only workload.
You can create a combination of mounted and read-only DB replicas for the same primary DB instance. For more information, see Working with Oracle Read Replicas for Amazon RDS in the Amazon RDS User Guide.
For RDS Custom, you must specify this parameter and set it to
mounted
. The value won't be set by default. After replica creation, you can manage the open mode manually.Type: String
Valid Values:
open-read-only | mounted
Required: No
- SourceDBClusterIdentifier
-

Constraints:
-
Must be the identifier of an existing Multi-AZ DB cluster.
-
Can't be specified if the
SourceDBInstanceIdentifier
parameter is also specified. -
The specified DB cluster must have automatic backups enabled, that is, its backup retention period must be greater than 0.
-
The source DB cluster must be in the same AWS Region as the read replica. Cross-Region replication isn't supported.
Type: String
Required: No
-
- SourceDBInstanceIdentifier
-
The identifier of the DB instance that will act as the source for the read replica. Each DB instance can have up to 15 read replicas, with the exception of Oracle and SQL Server, which can have up to five.
Constraints:
-
Must be the identifier of an existing Db2, MariaDB, MySQL, Oracle, PostgreSQL, or SQL Server DB instance.
-
Can't be specified if the
SourceDBClusterIdentifier
parameter is also specified. -
For the limitations of Oracle read replicas, see Version and licensing considerations for RDS for Oracle replicas in the Amazon RDS User Guide.
-
For the limitations of SQL Server read replicas, see Read replica limitations with SQL Server in the Amazon RDS User Guide.
-
The specified DB instance must have automatic backups enabled, that is, its backup retention period must be greater than 0.
-
If the source DB instance is in the same AWS Region as the read replica, specify a valid DB instance identifier.
